Based on the description above, it is the shipper of the package that is making the decision to delay the delivery of the package by a day in exchange for a better discount. If the shipper is making this decision, that's their call, not UPS'. The shipper has the option of relaying tracking info to their customer to keep them informed as to the delivery date. If the receiver has My Choice, they are fully aware of the scheduled day of delivery. Again, it's the shipper making the decision to delay delivery in exchange for a lower shipping cost - it's not UPS holding packages without consent of the shipper.
In the 2nd scenario listed, the package is arriving BEFORE the scheduled delivery date and we are holding it until the scheduled day of delivery, assuming there will be an additional package going to that address. The customer is still getting the package on the scheduled day of delivery so what's the issue?
The problem comes from the shipper not relaying that information to the customer, which many do with surepost. Also the service being used in ways not intended by management as a dispatch tool.
